Method for monitoring the quality of the primer layer applied on a motor-vehicle body before painting

摘要

A method for monitoring the quality of the primer layer applied to the body (2) of a motor vehicle prior to painting (enamelling) envisages provision of at least one manipulator robot (4) carrying a monitoring head (5). The monitoring head (5) includes a light source (6) constituted by an array of LED sources (60) and a videocamera (7) that are held in a position fixed with respect to one another whilst they are displaced with respect to the surface (S) to be monitored following the profile (T) of said surface (S). The signals at output from the videocamera (7) are processed by dividing the area monitored (I) into an array of sub-areas and executing the same processing procedure simultaneously on all the sub-areas.
